django-pgconnection provides primitives for overriding Postgres connection and cursor objects, making it possible to do the following:
Hook into SQL generation. For example, it is not possible to log every time a SQL statement is executed in Django or annotate SQL with comments so that additional metadata is logged when executing queries. The pgconnection.pre_execute_hook context manager allows one to hook into SQL before it is executed.
Route database traffic to a different database. Although Django provides the ability to construct custom database routers, routing to a different database has to be instrumented throughout code and can be tedious and error prone. The pgconnection.route context manager can route any database operations to a different database, even if it’s an external management command that has not been instrumented to use a different database.
The documentation has examples of how to use django-pgconnection.
Documentation
Installation
Install django-pgconnection with:
pip3 install django-pgconnection
After this, add pgconnection to the INSTALLED_APPS setting of your Django project.
In order to use connection routing and hooks, one must configure the DATABASES setting in settings.py like so:
DATABASES = pgconnection.configure({
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': 'mydatabase',
}
})
